REFRIGERATOR-ALARM.

Specification of Letters Patent.

Patented Nov. 26, 1907'.

Application filed June 12, 1907. Serial No. 378.548.

To all whom it may conce/m.'

Be it known that l', HENRY l?. KELLY, a citizen of the United States, residing at Shelton, county of Fairfield, State of Connecticut, have invented a new and useful liefrigcrater-Alarm, of which the following is a specification.

This invention has for its object to provide a simple and inexpensive alarm which may be readily attached to any refrigerator and will be operated by the rising of the water in the drip pan above a predetermined height.

/Vith these and other objects in view I have devised the novel alarm of which the following description in connection with the accompanying drawing is a specification, reference characters being used to indicate the several parts:

Figure 1 is an elevation of one end of the lower portion of a refrigerator illustrating the application thereto of my novel alarm, a drip pan under the refrigerator being in section, and the float and o perating arm being shown in full lines in the normal or inoperative position and in dotted lines in the operative position; and Fig. 2 is a plan view corresponding therewith, the 'float and drip pan being indicated by dotted lines.

10 denotes a base plate which is provided with holes to receive screws 1 1 and is adapted 'for attachment to the end of a refrigerator which is indicated by 12. The body of the refrigerator is supported by legs 13, one only being shown, leaving ample space under the refrigerator to receive a drip pan indicated by 14. The base plate extends a short distance infront of the refrigerator and carries a bell 15. The special style of bell used is, of course, immaterial, so far as the principle of the invention is concerned, it being sullicient for the purposes of this specification to state that the bell is provided with an actuating member 16 which is adapted to be engaged by an actuating arm, as will be more fully explained. Tn the present instance i have indicated an ordinary rotating spring actuated bell, the spring of which is wound by rotation of the bell and is released by a centrally placed actuating member.

17 denotes an arm which extends, in the present instance, downward and forward from the base plate and is provided with an eye 1S in which. a shaft 19 is mounted to oscillate freely and also to move loi'igitudinally, the ends of the shaft being reduced and l l l l l l f l l l l l l threaded. At the outer end of the shaft is an actuating arm 20 for the bell, which is detachably and adjustably secured to the shaft by means of a thumb-nut 21 engaging a thread. At the inner end ofthe shaft is an arm 22 which carries a float 23 adapted to lie within the drip pan. This arm likewise lis detachably and adjustably secured to the shaft by means of a thumb-nut 21 engaging a thread (see dotted lines in Fig. 2).

24 denotes a spring surrounding the shaft and acting against eye 1S and the float arm to hold the shaft inward. 25 denotes washers on the reduced ends of the shaft and engaging shoulders on the shaft (not shown). These washers are engaged by the inner faces of the actuating and -float arms, which are clamped between the washers and the thumb-nuts. By making the actuating and the '.[loat arms adjustable on the shaft, I make it easy to adjust the device to the vary ing conditions of use; for example, to different sized drip pans, and also make it convenient to so adjust the acti'lating arm and Afloat arm that the alarm will be sounded when the water has risen to any desired height in the drip pan so as to prevent the drip pan from getting inconveniently filled.

The function of the spring is to normally retain the shaft at the inner extreme of its movement with the actuating arm in alinement with the actuating member of the bell and the float in the drip pan. The float may be lifted above the drip pan by oscillation of the shaft and held there while the drip pan is removed, or it may be drawn out with the drip pan by sliding the shaft longitudinally in the eye, or the shaft may be drawn outward, as in dotted lines in Fig. 2 and the float drawn out .in front of the refrigerator and turned upward out of the way, as in dotted lines infFig. 2, in which position it will be retained by the spring or by the engagement of the actuating arm with the ifloor.

Having thus described 'my invention, T claim:

1. An alarm of the character described comprising a base plate, a bell carried thereby and provided with an actuating member, an arm extending from the base plate and provided with an eye, a shaft journaled in said eye, an actuating arm adjustably secured to the outer end of said shaft and adapted to engage the actuating member, an

arm adjustably secured. to the inner end of said shaft and a float carried by said inner arm.

2. An alarm of the character described comprising a base plate, a bell secured thereto and provided with an actuating member, an arm extending from the base plate and provided with an eye, a shaft mounted to oscillate in said eye, an actuating arm at the outer end of said shaft, a iloat arm at the inner end of said shaft, a float carried by the f float arm and a spring surrounding the shaft and bearing against the eye and the Heat arm, substantially as described, for the purpose specified.

3. An alarm of the character described comprising a base plate, a bell carried thereby and provided with an actuating member, an arm extending from the base plate and carrying an eye, a shaft mounted to oscillate in said eye, said shaft being provided with threaded ends, an actuating arm at the outer end of said shaft which is adapted to engage 4. An alarm of the character described comprising` a bell having an actuating member, an oscillatory longitudinally movable shaft, a bell actuating arm and a loat arm and float carried by said shaft, and a spring acting to retain the shaft at its inward position but permitting the shaft outward and the Hoat to be swung upward out of the way.

In testimony whereof I affix my signature,

1 in presence of two Witnesses.
